Star Trek: Voyager (1995-2001)
This show was really hit and miss. Seasons 1 and 2 were very bland. Season 3 was an improvement. Seasons 4 and 5 were good and then it fell apart in season 6. The last season was okay. Except for the finale. That was garbage. I haven't seen a worse ending since Mass Effect 3. That show really needed a guide. Instead it just kind of wandered all over.
